Tottenham Hotspur have revealed that Vincent Janssen "has undergone minor foot surgery", with the centre-forward now due to begin "a period of recovery and rehabilitation".
Janssen spent last season on loan at Fenerbahce having struggled to make his mark for Tottenham following a move from AZ in the summer of 2016.
The Netherlands international managed just two Premier League goals during his first season at Spurs, and had been widely expected to move on permanently this summer.
However, Janssen's chances of leaving the London club have been ended due to a foot problem which has required surgical intervention.
"Vincent Janssen has undergone minor foot surgery. He will now go through a period of recovery and rehabilitation overseen by our medical staff," read a statement on Tottenham's official Twitter account.
Janssen missed a lot of football at Fenerbahce last season due to an ankle fracture.
